Struct Answer 

pub struct Answer<T = AnswerValue> { /* private fields */ }

A normalized answer. Undecided answers retain evidence and call metadata.

Implementations

impl<T> Answer<T>

pub fn value(&self) -> Option<&T>

Decided value, or None for abstention.

pub fn decided(&self) -> bool

Whether this answer is decided. False and zero are decided values.

pub fn confidence(&self) -> f64

Reported decision confidence.

pub fn probabilities(&self) -> &Probabilities

Ordered probabilities, including for abstentions.

pub fn call(&self) -> Option<&Arc<Call>>

Metadata of the actual call, if reported.

pub fn raw(&self) -> Option<&Value>

Optional private provider response data, excluded from Debug and wire encoding.

pub fn with_call(self, call: Arc<Call>) -> Self

Attach reported call metadata.

pub fn with_raw(self, raw: Value) -> Self

Attach raw provider data for explicit inspection.

pub fn with_min_confidence(self, threshold: f64) -> Result<Self, Error>

Apply a threshold without restoring any previously undecided value.

Errors

Returns InvalidArgument if the threshold is nonfinite or outside [0, 1].

pub fn abstain(self) -> Self

Explicitly remove a decision while retaining all evidence.

impl Answer

pub fn revalidate(&self, question: &Question) -> Result<Self, Error>

Validate the retained provider candidate against the actual requested question. Existing abstentions remain undecided, including explicit provider abstentions.

Errors

Returns the normalization errors from make_answer if the retained candidate or distribution is incompatible with question.

pub fn typed<T: AnswerType>(&self) -> Result<Answer<T>, Error>

Project into a typed answer, checking type even when the answer is undecided.

Errors

Propagates conversion errors from AnswerType::from_answer_value, including a type mismatch even when this answer is undecided.

Trait Implementations

impl<T: Clone> Clone for Answer<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Answer<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Answer<T>

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
